Talented but injury-prone Filip Krajinovic had an amazing run in 2017, gaining 200 positions in the ATP rankings to finish just outside the Top 30 after reaching the final at Paris Masters. Filip cracked the Top 30 for the first time in March but his body couldn't follow the desired pace, struggling with injuries and missing the entire action in April, May and June.

Filip has won just one match after Miami and he will seek new triumphs with a new coach, as he decided to end his collaboration with Petar Popovic. They started working together in the summer of 2017 and Petar improved Filip's game to propel him into the Top 30, giving him a chance to play for Masters 1000 title.

In addition, Krajinovic will have to skip the Davis Cup Play-ff tie against India this weekend at home in Kraljevo due to a shoulder injury, unable to lead his country in the absence of Novak Djokovic. Now, Dusan Lajovic and Laslo Djere will play for Serbia in singles rubbers and Serbia is still the favorite against India on clay.

“I had to cancel my participation in the Davis Cup,” Krajinovic told Serbian media. “I’m really sorry, but my shoulder is not in the brightest condition. It hurts. I can't serve until the end of next week, so it automatically meant that I could not play in Kraljevo.”

"After incredible and crazy last 12 months where Filip got progression from 126 to 26 on ATP ranking Filip and my self-decided to finish our relationship player-coach! So from now on, I am open for new challenges," said Petar Popovic.
